Hello!
We using the spine with timeline on game launched for show Intro for player first launch.
Everywhere it's work okay, but on a small number of devices we have spine crush. We can't reproduce this issue on our devices, but players is write to us with this problem. I've attached the crush stack trace.

Spine package version: spine-unity-4.1-2024-02-26.unitypackage
Unity version: 2022.3.21f1
Platform: Android
Devices: Redmi Note 11 Pro, Galaxy S24, OnePlus 10R 5G

How we can resolve this issue?

To address the issue of Spine crashing on certain Android devices when using Unity Timeline, it is important to ensure that you are using the latest version of the spine-unity runtime. Since you are using version 4.1, consider updating to the latest 4.2 version, as it may contain bug fixes that could resolve the issue. Additionally, it would be helpful to gather more detailed logs and stack traces from the affected devices to better understand the cause of the crash. If the problem persists, you might want to create a minimal Unity project that reproduces the issue and send it to Esoteric Software for further investigation.

@Midial Sorry to hear you're having troubles. Please note that the 4.1 unitypackage you're using (2024-02-26) is not the latest available (2024-06-19). When encountering issues, please always check first whether the latest package fixes your issue:

If it does not resolve the issue:
My best guess for your above out-of-range array access to happen is if the loaded (binary) skeleton format does not match your spine-unity runtime version. So i.e. the exported skeleton data file is of an older or newer version than your runtime supports. Have you perhaps modified the spine-unity runtime code, and i.e. changed any of the version checks?

If you can't reproduce this issue locally, are you perhaps using any download mechanism like Addressables, Asset Bundles or the like? If so, please make sure that there are no outdated download packages left which might be loaded accidentally instead of the correct package.

    Harald Thank you for fast answer! we'll try this solutions.

      Hello! We have updated the spine runtime in our project and re-exported all spine files to the following version:

      The crashes are still present. All of them are related to timeline: Spine.RGBATimeline.Apply, Spine.RotateTimeline.Apply.

      Unity version: 2022.3.21f1
      Platform: Android

      Any ideas on how we can fix this?

        @Midial Sorry to hear that. If the issue persisted with the latest Spine 4.2 Editor version, could you please create a minimal Unity project which still shows this issue? You can send it as a zip package to contact@esotericsoftware.com, briefly mentioning this forum thread URL so that we know the context. Then we can have a look at it.
